  • 1 outlier Dr. Lynne Talley

    Data Type: NITRAT
    Action: Update Needed
    Note:
    going over the final plates for the Pacific atlas, Sharon spotted a nitrate outlier on P4 at station 40.
    
    It looks very questionable to me
    
    File:  http://cchdo.ucsd.edu/data/onetime/pacific/p04/p04w/p04why.txt
    
    Station 40, bottle 1, 2245.6 dbar, nitrate of 35.13 at theta of 1.804.
    In the nitrate/theta plot, this is clearly an outlier. 
    
    On the nitrate vertical section, there isn't any water this low anywhere nearby.  I'm attaching the jpg of the section along with the property plot - our section contouring must have just ignored it.
    
    I'd suggest possibly editing the quality flags to indicate "3" since it had escaped all quality control checks before, probably no way to easily check on whether it's a good analysis or not.

    TALLEY, LYNNE would like the following action(s) taken on the data: Other: Other: change quality flags
    
    Any additional notes are:
    NITRIT on station 40 improbably large at all bottles. Quality flag should be changed to 4.  Since only QUALT1 flags were available in the online file that was edited, the file that is being sent has the flagging in QUALT1.  However, a new file with QUALT2 column should be generated by the WHPO and these flagging changes incorporated there.

    Note:
    I have replaced the previously online bottle file for P04W with the bottle file containing newly merged CFCs. Data updates were sent by D. Wisegarver and merged by D. Muus. New updated sumfile was also created by D. Muus. all previous files have been moved to original subdirectory. and have been renamed. All references have been updated to reflect this change. 
    
    1. New CFC-11 and CFC-12 from John Bullister, PMEL anonymous ftp site on Aug 31, 2001:
    wocecfc/freon/pacific/FINALDQE/RELAXED/tps10_CFC_DQE.dat
    merged into web SEA file as of Aug 21, 2001: P04W (20010326WHPOSIOKJU)
              
    The first revised CFC file received this summer was missing Station 8 because it was not in the SUMMARY file: 
    /usr/export/html-public/data/onetime/pacific/p04/original
    20010709_CFC_WISEGARVER_P04/20010709.165933_WISEGARVER_P04_tps10_CFC_DQE.dat
    
    One file contained new CFC data for all three legs. No SEA file QUALT2 words so added QUALT2 identical to QUALT1 prior to merging. New CFC data file appears to have SAMPNO and BTLNBR swapped with respect to .SEA file data.  Checked that .SEA file SAMPNO same as CFC file "btlnbr" by comparing to Sta#, Cast# and CTDPRS.
    
    2. SUMMARY file (20010326WHPOSIOKJU) has "INT" (interpolated?) as NAV entry numerous times. "INT" not a NAV code per WOCE Manual.
    
    EVENT CODE is BO, EN, BE rather than normal sequence of BE, BO, EN. All three position and time entries for each station are identical since this is a Pre-WOCE cruise.
    
    No Station 8 in SUMMARY file although .SEA file contains Station 8, Cast 1 with 24 bottles (see Item 3 below).
    Added Station 8 data to SUMMARY file per John Toole info received Aug 28, 2001. Left rest of SUMMARY unchanged.
    
    3. Station 8, Cast 1 in Mar 26, 2001 .SEA file has 24 bottles with oxygen, nutrients, and 5 levels of CFCs.  Message from Chief Scientist, John Toole, Aug 28, 2001, says Station 8 not
    used because CTD sensor guards left on making the CTD temperature suspect and the CTD salinities useless. He said bottle data can be used and noted air vents open on bottles 14, 19 and 22.
    Changed all CTDSAL quality codes from 2 to 4 (bad measurement).
    Changed BTLNBR quality codes for bottles 14, 19 & 22 from 2 to 3 (leaking).
    Changed CTDPRS for Station 8 to final calibrated pressures supplied by John Toole.

  • Info needed for new CFC James Swift

    Date: 2001-08-28
    Data Type: CTD/SUM
    Action: Update Needed
    Note:
    John Toole has kindly given the WHPO enough information to reconstruct the P04 Station 8 entry in the .sum file.  (It had been deleted because there were no CTD data from that station due to an error.)  We can thus keep Station 8 in the bottle data file.  We have only the old CFC data for Station 8.  We can make the change to the new CFC scale, or even add quality bytes, if you tell us how.  Or you can send us revised Station 8 CFCs.  Thanks.  Jim

    Note:
    PO4W has Station 8 rosette data on web SEA file (20010326WHPOSIOKJU) but not in web SUMMARY file (20010326WHPOSIOKJU)
    
    This is a Pre-WOCE cruise, TPS-10N, R/V Moana Wave, Palau, Feb 6, toMajuro, Mar 4, 1989.  EXPOCODE 32MW803_1. Chief Scientist:   John Toole (WHOI) On board CFCs:     John Bullister
    (WHOI) CFC Documentation: R. Weiss/R. Van Woy
    
    Station 8, Cast 1 SEA file has 24 bottles with oxygen, nutrients, and 5 levels of CFCs. No Station 8 data in revised CFC file from Wisegarver, May 2001.
    
    The Chief Scientist's report in the .DOC file leaves out Station 8 in all CTD correction tables but the Nutrient lab temperature table contains Station 8. The "Cruise Overview" section mentions 2 test casts, Station 3 as the first real station at 125m bottom depth, and then a CTD instrument change at Station 27. I could find no other mention of Station 8.  Sta. 8 appears to be a Philippine Trench station, 6501.3db max sample depth, per SUMMARY file positions for Stations 7 and 9.
    
    The WHOI Technical Report (WHOI-91-32) has Station 7 on Page 76 and Station 9 on Page 77 but no data for Station 8.  Plate 1 (Station Position Plots) does show Station 8 at the same latitude as the adjacent stations.

  • precision outside orighnal WOCE standards; meets "relaxed" stnds David Wisegarver

    Date: 2001-06-29
    Data Type: CFCs
    Action: DQE Complete
    Note:
    The precision of the CFC-11 and CFC-12 measurements fell outside of the original WOCE standards of 1% or 0.005 pmol/kg with an estimated precison of 1.3% or 0.006 for CFC-11 and an estimated precision of 1.9% or 0.002 pmol/kg for CFC-12.  Estimates of presision were based on the median value of percent deviation for mean concentrations > 0.5 pmol/kg and median standard deviation for mean concentrations less than or equal to 0.5 pmol/kg.
    
    Due to bottle contamination experienced during the initial phase of the project, the calculated deep CFC concentrations were variable, in stpite of efforts to correct for the problem.  The standard deviation of samples in the deep, presumable zero CFC concentration water was 0.01 for CFC-11 and 0.007 for CFC-12 during leg 1, but was reduced to 0.04 and 0.003 for CFC-11 and CFC-12 respectively by leg 3.  This lever of scatter can be seen throughout the water column.
    
    Based on the precision of the replicate samples and the scatter due to bottle contamination, this data set does not meet the original WOCE quality standards [1.3% or 0.006 for CFC-11 and 1.9% or 0.002 pmol/kg for CFC-12], but does fall within the relaxed standards of 3% or 0.015 pmol/kg.

    Date: 2001-05-08
    Data Type: NITRIT
    Action: Update Needed
    Note:
    The quality flags for nitrite (NITRIT) on station 40 must all be set to "bad" - I see that bad flags on adjacent stations are "5"'s.
    
    If you want, I can plot the section for you with and without these data - they are clearly impossible (uniformly 0.13 throughout most of water column - there isn't any way anywhere in the world that you would find such uniformity to such great depth).
    
    Should I just go ahead and do this and send you the edited file with a date stamp on it?

  • See note: Peter Salameh

    Date: 2000-07-24
    Data Type: CFCs
    Action: Update Needed
    Note:
    There are two problems with the TPS10 CFC data.  The first has to do with contaminated bottles.  Nearly all of the analytical equipment, including the WHOI 10-liter Niskin bottles used for the majority of the hydrographic work, were sent to Majuro in a shipping container which was severely contaminated with CFCs, probably originating from packing foams used for other equipment in the container.
    
    There were 4 types of bottles used during this cruise, each with a different initial CFC blank, and each cleaning up at a different (about exponential) rate.  Ricky and I did our best to fit the blanks for each bottle type to an exponential as a function fo time.  To give you some idea, the initial blanks (in pmol/kg) at the start of each leg for each bottle type were:
    
    Leg1                          CFC-11    CFC-12
    
    10  liter WHOI Niskin  0.047     0.019 
    2.4 liter Niskin           0.025     0.012 
    10  liter SIO Barron    0.047     0.019 
      
    Leg2                          CFC-11    CFC-12
    
    10  liter WHOI Niskin  0.022     0.005 
    2.4 liter Niskin           0.026     0.004 
    
    
    
    Leg3                          CFC-11    CFC-12
    
    10  liter WHOI Niskin   0.009     0.005 
    2.4 liter Niskin            0.006     0.004 
    10  liter Miami Niskin  0.004     0.006 
      
    When determining these blanks we also had the problem that CFC-free water was not sampled for all bottle types at all times, so some guess work was involved.  As I write this, Ray reminds me that we have already written a detailed report on this.  I have attached this as PostScript file "text.ps" if you would like all the details.
    
    The second problem I discovered recently when comparing the WHPO database with our CFC database, as part of the WOCE synthesis.  For TPS10 leg3, I found a few values where the two databases do not match, and also quite a few samples where the WHPO file shows CFC values of 0.0 where we report no value.  These were clearly merging problems at the old WHPO at WHOI.  I have attached the list of mis-matches and a correct version of the tps10 leg3 CFC data.  I will send the corrected data to the WHPO next week (see below).
    
    Please note that all the SIO TPS data (TPS10, 24 and 47) are still on the SIO 1986 standard scale.  All the other SIO data at the WHPO are on the SIO 1993 standard scale.  Early next week I will update the WHPO database with SIO 1993 values for the TPS cruises (the conversion from SIO 1986 to SIO 1993 requires dividing CFC-12 values by 0.9874 and CFC-11 values by 1.0251).  If you would like, I will email you a copy of these data when I send them to the WHPO.

    Note:
    I'm working with Lou Gordon on the GODS Pacific project.  No doubt you'll be hearing more from me.
    
    In regard to the "P10 - Nitrate" note Lou sent to you the other day - the data listed under the "NITRATE" column is in fact the total of "Nitrate AND Nitrite" or N+N.  You are correct in stating that to obtain NITRATE only, you must subract out the corresponding NITRITE value.   Again, the units of umol/Kg are correct for all nutrients.
    
    To clarify, I obtained the P10 data (p10hy.txt) from the WOCE website that your PACIFIC data listing website linked - http://whpo.ucsd.edu/data/onetime/pacific/p10/index.htm.
    
    After downloading  and checking cruise TPS10 (WOCE p04ehy.txt, p04chy.txt, p04why.txt) from the WOCE website, I've determined the same situation to be true.  The data listed under the "NITRATE" column is actually NITRATE and NITRITE combined.  The units of umol/Kg are correct for all the nutrients in the WOCE files.
